Cantilevers. 4-39 the section only, so here the shear ordinates are drawn downward on the line a £, and equal W in every case. II. Cantilever with Uniformly Distributed Load (Fig. 395), the load being represented by the weight of the beam. Con- sidering the beam hinged successively at A, B, c, D, and E, the loads on the right may be successively concentrated at their middle points, and the Bending Moments become: At A- Wx- 4 ><S/ W/X32 W / r At c= —x- = W/x - cc 24 8 W / i At D = —x- =W/x— a 48 32 = 32 i=i and at E = nothing, as shewn by diagram, and as the ordinates vary as the square of the abscissae at a If, the curve is a parabola with b as vertex. Shearing Force on right of section A = W, at section B =f W, W W and at c D and E, — •, — , and nothing respectively, as shewn by diagram on a^br III.
